65-66 Manual Trans Brake Boosters

I haven't touched it...

I decided to hydro boost :)
Hi mdjay. I would like to buy this booster if you're not going to use it:

I am having a problem with a '65 fb. I am installing a hydraulic throwout bearing from Dark Horse that was represented to be using a JMC master cylinder. I presently have a Trans Am Racing power disc brake conversion kit, and its booster interferes with the clutch master cylinder.

The Trans Am Racing kit uses a CNC carved billet aluminum spacer that mounts the four studs of a 7" booster, brand unknown. Four studs come out the back of the spacer and go through the pedal support bolt holes, to be secured with nuts from the interior. This setup lacks the bell crank assembly of your booster, so its centerline has to line up with the brake pedal's attachment point. This leaves the booster hanging down about a half inch too low, causing the interference with the clutch master cylinder.

If you think your bell crank bracket and booster will clear, and also be compatible with the Maier Racing one-piece underhood brace, then I want one.

I too run a Trans Am Racing booster. When I did my hyd TO bearing setup I was able to move the mounting location over by incorporating my pedal stop into my clutch pedal assembly.

gp001, thanks for the reply and the link. You've come up with a great solution. I'll be adding a pedal stop to my setup; I think I'll use a rubber axle snubber I have laying around.

mdjay, as you may have put two and two together, I ordered one of your Scott Drake boosters yesterday. Looking forward to delivery. That purchase pushes this hydraulic TO bearing conversion up over the $1000 mark. And that doesn't count the complete duplicate aftermarket Z-bar setup, the two diaphragm clutch kits, the billet steel flywheel, the '95 T-5z, the solid iron bearing retainer, the billet steel countergear stabilizer, the MGW shifter (and two handles), the crossmember, the spacer, and the three or four TO bearings I've been through, trying to get a functional tranny. Someday.
